We center on the Okiku Doll at Mannenji Temple, famous for its ever-growing human hair. Purchased in 1918, the doll is believed to house the spirit of a young girl named Kikuko. While priests periodically trim the hair, skeptics suggest the "growth" is an illusion caused by loosening glue or humidity. The topic also explores Japanese hair superstitions and animism, specifically the belief that inanimate objects can become ensouled over time.
